Jennifer A. Lewis: Revolutionizing Materials Science with the 2025 James Prize

Curator: Dr. Sudipta Saha, Ph.D.

Jennifer A. Lewis, the Hansjörg Wyss Professor of Biologically Inspired Engineering at Harvard University, has been awarded the prestigious 2025 James Prize in Science and Technology Integration by the National Academy of Sciences. This recognition highlights her ground breaking research in the programmable assembly of soft functional, structural, and biological materials.

Lewis has pioneered work in integrating various scientific fields, including materials science, soft matter physics, additive manufacturing, bioengineering, and stem cell biology. Her lab focuses on developing advanced materials, such as electrically and ionically conductive inks for micro-scale printed devices like electronics and batteries. Additionally, Lewis’s work on stem cell-derived organoids has enabled the creation of 3D organ-on-chip models and vascularized tissues, which hold promise for drug screening, disease modeling, and therapeutic applications.

The James Prize, awarded by the National Academy of Sciences, recognizes outstanding contributions made by individuals who integrate knowledge across multiple disciplines to address pressing challenges. Lewis’s innovative approach, exemplified in her multidisciplinary work, has transformed the way soft materials and biological systems are designed and utilized. The prize includes a $50,000 award, underscoring her exceptional impact on science and technology.

With numerous accolades to her name, including the NSF Presidential Faculty Fellow Award and election to the National Academy of Sciences and the National Academy of Engineering, Lewis’s work continues to reshape the future of biologically inspired engineering.

Lifelong Contraceptive Device for Men: Mechanical Switch to Control Fertility on Wish

Reporter and Curator: Dr. Sudipta Saha, Ph.D.

There aren’t many options for long-term birth control for men. The most common kinds of male contraception include

  • condoms,
  • withdrawal / pulling out,
  • outercourse, and
  • vasectomy.

But, other than vasectomy none of the processes are fully secured, comfortable and user friendly. Another solution may be

  • RISUG (Reversible Inhibition of Sperm Under Guidance, or Vasalgel)

which is said to last for ten years and no birth control pill for men is available till date.

Recently a German inventor, Clemens Bimek, developed a novel, reversible, hormone free, uncomplicated and lifelong contraceptive device for controlling male fertility. His invention is named as Bimek SLV, which is basically a valve that stops the flow of sperm through the vas deferens with the literal flip of a mechanical switch inside the scortum, rendering its user temporarily sterile. Toggled through the skin of the scrotum, the device stays closed for three months to prevent accidental switching. Moreover, the switch can’t open on its own. The tiny valves are less than an inch long and weigh is less than a tenth of an ounce. They are surgically implanted on the vas deferens, the ducts which carry sperm from the testicles, through a simple half-hour operation.

The valves are made of PEEK OPTIMA, a medical-grade polymer that has long been employed as a material for implants. The device is patented back in 2000 and is scheduled to undergo clinical trials at the beginning of this year. The inventor claims that Bimek SLV’s efficacy is similar to that of vasectomy, it does not impact the ability to gain and maintain an erection and ejaculation will be normal devoid of the sperm cells. The valve’s design enables sperm to exit the side of the vas deferens when it’s closed without any semen blockage. Leaked sperm cells will be broken down by the immune system. The switch to stop sperm flow can be kept working for three months or 30 ejaculations. After switching on the sperm flow the inventor suggested consulting urologist to ensure that all the blocked sperms are cleared off the device. The recovery time after switching on the sperm flow is only one day, according to Bimek SLV. However, men are encouraged to wait one week before resuming sexual activities.

Before the patented technology can be brought to market, it must undergo a rigorous series of clinical trials. Bimek and his business partners are currently looking for men interested in testing the device. If the clinical trials are successful then this will be the first invention of its kind that gives men the ability to control their fertility and obviously this method will be preferred over vasectomy.
